Group Title
I have the following information:
\[n=p^2q\]
\[k \ge 4\]
\[0<v<n\]
\[0 \le x < pq\]
\[y=\lceil \frac{(vx^k) \mod n}{pq} \rceil \cdot (kx^{k1})^{1} \mod p\]
I want to show:
\[\sum_{i=0}^{k}\left(\begin{matrix} k \\ i \end{matrix}\right) x^{k1}(ypq)^i \equiv x^k+kypqx^{k1}\]
the congruence is mod n

i made a mistake \[\sum_{i=0}^{k}\left(\begin{matrix} k \\ i \end{matrix}\right) x^{ki}(ypq)^i \equiv x^k+kypqx^{k1}\] I'm trying to follow a proof but i don't know how they got from that one part to the other part

ask me next semester when I've taken cryptography, and I might be able to help you, but right now, I haven't got a clue.

only the first two values of i will matter (i=0,1) for i>1 you have a \((pq)^2\) part which is \(p^2qq=nq\) which is zero nod n

george what kind of math have you had?

Zarkon Group TitleBest ResponseYou've already chosen the best response.2
\[{k\choose i}x^{k1}(ypq)^i\] for \(i\ge2\) \[{k\choose i}x^{k1}(ypq)^i={k\choose i}x^{k1}(y^i)(pq)^{i2}p^2qq\] \[=\left({k\choose i}x^{k1}(y^i)(pq)^{i2}q\right)\times n\]

you are so smart to notice the first two values will only matter since n mod n is like totally 0 thanks zarkon

not very much. I'm taking intro to number theory, and cryptography next semester.

It certainly sounds fun. I'm definitely enjoying my abstract algebra class right now. We had the barest hints of some number theory in discrete math so I'm not completely helpless.

From my experience, I don't like differential equations very much. Granted, I've never had a full course in it, but it just isn't my thing.

I'm personally more of an algebra person. Stats was interesting at first, but then it got boring.
